This overview sets the scene for the various modules in the Renewables 2024 Global Status Report Collection. It provides high-level trends on the status of renewables in the wider fossil fuel-dominated energy system in the context of global challenges such as climate change, development goals and the geopolitical landscape. Urgent …
Changes in the ocean's carbon cycle as a result of the greenhouse effect are already under way, says a climatologist. As carbon dioxide (CO 2 ) dissolves in water, the oceans could dampen global warming by absorbing some of the excess co2 that human activity produces. But a climate model …
Although Chloroflurocarbons (CFCs) and various other related chemicals are being phased out as they damage the ozone layer, it has been more than difficult to find a suitable and commercially feasible replacement for them in car air conditioning. Daimler-Benz, Germany's automobile giant, is now testing an air conditioner that uses …
increasing levels of carbon dioxide (CO2) in the atmosphere could result in some fundamental changes in the growth pattern of plants, say scientists at the University of Michigan Biological Station, usa. While studying the impact of atmospheric conditions in near future, these scientists have discovered that trembling aspen trees grow …
efforts to cut global carbon dioxide ( co 2 ) emissions have not yielded much success. Recent findings indicate that the emission from burning of fossil fuels has continued to increase. The highest levels of co 2 were recorded in the Asia Pacific, which include India, China and the Middle …
norway's hottest environmental issue at the moment is the planning of two gas-fuelled power plants, which will lead to the emission of 2,000,000 metric tonnes of carbon dioxide ( co 2 ) annually. Permission for setting up the plants was granted by the Norwegian parliament before industrialised countries agreed, in …
recycling paper is not the best option to protect the environment. Say this to the archetypal "green' activist and you will be labelled "pro-industry' and insensitive to the environment. You are bound to be reminded that the forests
each year, thermal features such as hot springs at the Yellowstone national park in the us emit millions of tonnes of carbon dioxide (co2), the most important greenhouse gas, according to researchers at Pennsylvania State University (psu), usa. This is more than the emissions from a typical industrial power plant, …
concerns that burning of fossil fuels could increase levels of co 2 in the atmosphere leading to climate change has caused wrangling among the world's politicians, scientists and environmentalists for years. But it has seldom been regarded as a business opportunity. Now, three enterprises in the uk are promoting "carbon …
THE COMPLETE PICTURE: Televisions all over the world display only 88 per cent of the image broadcast by TV stations. Now, Korean-based electronics company, Samsung is developing televisions that will display the missing 12 per cent. Called HiTron TV sets, these televisions are 2.5 centimetres wider than usual. Conventional TV …
deficiency of iron in the microscopic plant-like organisms that populate the seas - called phytoplankton - may have interfered in the carbon dioxide cycle and contributed to global warming. Scientists are now investigating reversal of this process. Confirmation of this fact will provide answers that may help combat global warming. …
Researchers at Colorado State University, USA, believe that they have found an environmentally friendly method of dealing with rootworms that ravage cornfields. The experiment were based on the discovery that rootworm larvae search for the roots of the plant by detecting the carbon dioxide (CO2) that roots emit. Louis B …
chemists in the us have developed carbon dioxide ( co2 ) soluble detergents that could be used for dry-cleaning purposes. The liquid co2 would be used in dry cleaning machines as a solvent. With the use of the detergents, dry-cleaners would lose their characteristic smell. The detergent would also reduce …
With the world increasingly worried about climate change, a new scheme is being cooked up to deal with the problem. The World Bank has an ingenious proposal - which is still confidential - in which the Bank would buy and sell, as the most "honest broker", the rights of present …
A US study shows that increasing concentrations of carbon dioxide (CO 2 ) in the atmosphere result in improved photosynthesis, helping trees grow faster. Scientists at the University of Georgia, USA, have evaluated the response of loblolly pines to increasing concentrations of CO 2 and measured the photosynthesis, respiration and …
the cement industry has a larger share in global emissions of carbon dioxide ( co 2 ) than that of aircraft worldwide, estimates an industry scientist. It contributes about seven per cent of the global co 2 output. This puts it in the third place in the list of contributors …
the latest thing that is brewing up a storm in Europe is a new self-cooling drink can which could cause global warming. Britain is now seeking new ways to ban the can. "If the can captures, say 10 per cent of the uk market by the year 2000, it would …
A survey of 10,076 households conducted by the NPD Group Inc in the US found that computers switched on at homes sit idle for 54 per cent of the time. The Sierra Club, a group of environmentalists, has estimated that a computer running for more than three hours a day …
A prototype solar device that produces enough hot air from the sun's rays to drive the turbines of a 50 kw power station has brought the prospect of cheap, solar-generated electricity a step closer. The solar energy collector has been successfully tested by Israeli researchers at the Weizmann Institute of …
Monitoring the effect of rising carbon dioxide (CO) concentrations and climatic changes on Europe's forests is the aim of a collaborative project across eight European countries and Australia. The project is jointly funded by the Forestry Commission of UK and the European Union under the Environment and Climate Programme 1994-1998. …
